A preferred embodiment of the present invention will now be described in detail with reference to the drawings. It should be noted that the relative arrangement of the components, the numerical expressions and numerical values set forth in these embodiments do not limit the scope of the present invention unless it is specifically stated otherwise.

FIG. 1A is a view showing an example of an image processing system according to an embodiment of the present invention. In FIG. 1A, reference numerals 101 and 103 denote devices as image processing devices having a network interface and scanner function; and 104, a device having a network interface but no scanner function. The devices 101, 103, and 104 are connected to PCs 102, 105, and 106 having a network interface across a network 107.

FIG. 1B is a view for explaining the internal arrangements of the PCs 102, 105, and 106 and devices 101 and 103 included in the image processing system.

The PC comprises a memory 110 for storing an IP address and computer name as identification data of the PC, a retrieval unit 115 as a retrieval means for retrieving a device connected to the network, a transfer unit 120 as an identification data transfer means for transferring the identification data to a device, and a user interface 125 which, if a plurality of devices are found by retrieval by the retrieval unit 115, displays a list of the devices to the user, and allows the user to select a device to which the identification data is to be transmitted.

The devices 101 and 103 comprise a scanner unit 130 as an image scanning means for scanning an image and outputting the image data, a memory 140 as a storage means for storing a destination of the image data output from the scanner unit 130, a transfer unit 150 as an image data transfer means for transferring the image data to the destination stored in the memory 140, a receiving unit 160 for receiving the identification data transferred from the transfer unit 120, a registration unit 170 as a registration means for registering the received identification data as a destination of image data in the memory 140, and a user interface 180 which allows the user to select a PC to which image data is to be transferred, from a plurality of PCs stored as destinations in the memory 140.

FIG. 2 is a sequence diagram showing an operation performed for the devices 101, 103, and 104 when a driver is installed in the PC 105. In FIG. 2, reference numeral 201 denotes a packet for determining whether the device 101 is connected across the network 107; 202, a packet for determining whether the device 103 is connected across the network 107; and 203, a packet for determining whether the device 104 is connected across the network 107.

Reference numeral 204 indicates a response from the device 101 to the connection confirmation request packet 201, and denotes a packet which notifies the PC 105 that the device 101 is connected to the network. Reference numeral 205 indicates a response from the device 103 to the connection confirmation request 202, and denotes a packet which notifies the PC 105 that the device is connected to the network. Reference numeral 206 indicates a response from the device 104 to the connection confirmation request packet 203, and denotes a packet which notifies the PC 105 that the device 3 is connected.

Reference numeral 207 denotes a packet for determining whether the device 101 whose connection is confirmed has a scanner function. Reference numeral 208 indicates a response from the device 101 to the scanner function confirmation request packet 207, and denotes a packet which notifies the PC 105 that the device 101 has a scanner function. Reference numeral 209 denotes a packet for determining whether the device 103 whose connection is confirmed has a scanner function. Reference numeral 210 indicates a response from the device 103 to the scanner function confirmation request 209, and denotes a packet which notifies the PC 105 that the device 103 has a scanner function. Reference numeral 211 denotes a packet for determining whether the device 104 whose connection is confirmed has a scanner function. Reference numeral 212 indicates a response from the device 104 to the scanner function confirmation request packet 211, and denotes a packet which notifies the PC 105 that the device 104 has no scanner function.

FIG. 3 is a sequence diagram showing an operation of registering the computer name of a PC into devices having a scanner function.

In FIG. 3, reference numeral 301 denotes a packet for requesting the device 101 to register the computer name of the PC 105. Reference numeral 302 indicates a response from the device 101 to the computer name registration request 301, and denotes a packet which notifies the PC 105 that the registration is normally complete. Reference numeral 303 denotes a packet for requesting the device 103 to register the computer name of the PC 105. Reference numeral 304 indicates a response from the device 103 to the computer name registration request 303, and denotes a packet which notifies the PC 105 that the registration is normally complete. Since the device 104 has no scanner function, no computer name registration request packet is transferred from the PC 105.

FIG. 4 is a flowchart when a driver is installed in the PC 105. Referring to FIG. 4, in step S401, connection confirmation request packets are confirmed by broadcast across the network 107. This step is equivalent to the operation of transferring the packets 201, 202, and 203.

Then, in step S402, a timer is set to wait for a response from a device for a period of time. In step S403, the timer waits for a response from a device on the network. If there is a response, the flow advances to step S404; if not, the flow advances to step S405. In step S404, the device having responded in step S403 is stored in a found device list. In step S405, whether the time of the timer set in step S402 has expired is determined. If the time has expired in step S405, the flow advances to step S415; if not, the flow returns to step S403.

In step S415, whether no device is found is determined. If there is no response before the time of the response waiting timer expires, it is determined that no device of interest exists on the network, and the installation is terminated. If even one device is found, the flow advances to step S406.

In step S406, whether the process of checking the presence/absence of a scanner function has been performed for all the devices found in step S404 is determined. If this confirmation has been done for all the devices, the flow advances to step S410; if not, the flow advances to step S407.

In step S407, one device which is found in step S404 and has not been confirmed whether it has a scanner function is selected, and an inquiry is made to determine if it has a scanner function. This processing is equivalent to the operation of transferring the packets 207, 209, and 211. In step S408, the timer waits for a response from the device having undergone the confirmation of the presence/absence of a scanner function in step S407. If it is confirmed by the response that the device has a scanner function, the flow advances to step S409; if not, the flow returns to step S406.

In step S409, the device found to have a scanner function in step S408 is stored. In step S410, the number of devices with a scanner function stored in step S409 is determined. If the number is two or more, the flow advances to step S411. If the number is one, the flow advances to step S413. If the number is zero, the flow advances to step S414.

If it is determined in step S410 that a plurality of devices with a scanner function are found, the flow advances to step S411 to display a window (FIG. 5) for selecting, from a plurality of devices having a scanner, a device in which the computer named of the PC is to be registered as an address, thereby prompting the user to select a device by using the user interface. It is also possible to select a plurality of devices in which the computer name of the PC is to be registered as an address.

In step S412, the computer name of the PC is registered in the device selected in step S411. This processing is equivalent to the packet transfer/receiving operation shown in FIG. 3.

If it is determined in step S410 that there is one device having a scanner function, the flow advances to step S413 to register the computer name without displaying the device selection window shown in FIG. 5.

If it is determined in step S410 that there is no device having a scanner function, the flow advances to step S414 to display a re-retrieval window shown in FIG. 6, thereby allowing the user to make a decision.

Note that although the device having responded in step S403 is stored in the found device list in step S404, it is also possible to always hold the found device list, and update its contents in accordance with the device having responded in step S403. In this case, in step S406, whether the process of confirming the presence/absence of a scanner function has been performed need only be determined for a new device added to the found device list. The address is registered in a new device only when a difference from the last device configuration is detected. Also, if a device which is registered in the found device list cannot be found on the network, it is possible to display this information on the user interface to allow the user to confirm the information, and prompt the user to perform re-retrieval.

Also, the polling operation is performed using the timer in steps S402 to S405 of the above embodiment, but the present invention is not limited to this, and it is also possible to re-retrieve devices a plurality of number of times at arbitrary timings.

Although the PC scans devices on the network in the above embodiment, the present invention is not limited to this, and a device may also send (broadcast), to the network, information (a packet) indicating that the device has a scanner function at each predetermined period. In this case, the PC on the network receives the packet (scanner function installed device notification) broadcast from the device, and, on the basis of the received notification, determines whether a new scanning device is added to the network. If a new scanning device is added to the network, the user of the PC is inquired of whether to register the identification data (e.g., the IP address and PC name) of the PC as an address into the added scanning device. If this registration is to be performed, the identification data of the PC and a registration request are sent to the device in the same manner as in the above embodiment.

If a device connected to the network in the past cannot be found any longer after re-retrieval, this device is stored as device disconnection, and, if a device found on the network after that is the device which is stored as device disconnection, all drivers for this device existing in other PCs are notified of the new and old pieces of device information (by broadcast or the like).

Each PC having received this notification rewrites the address of the driver to the new device information.

If an unidentified device is found, each PC on the network transfers, to drivers of other PCs, information indicating that the device address has changed, thereby rewriting the addresses of the other drivers.

Note that if a device tries to send a scanner image across the network to a PC registered as an address in the memory 140 and an error occurs because there is no such address, this error is displayed on the user interface 180, the image data is retransferred, and, if the number of successive errors has reached a predetermined value, the error address is erased from the memory 140.

Also, identification data is transferred from a PC to a device when a driver is installed in the above embodiment, but the transfer timing of this identification data is not limited to this.

In the above embodiment, an address can be automatically registered in a scanning device, so even if the number of PCs as addresses for the scanning device increases or decreases on the network, this increase or decrease can be automatically controlled. In addition, even if the address of a device or PC is changed, this change can be automatically traced.
